Beam selection method and network element

Abstract

The present disclosure provides a beam selection method and a network element. The network element includes a first network element in a communication network, including: a receiving unit configured to receive measurement results of a terminal for first information transmitted via at least a part of first beams; a processing unit configured to determine a preferred beam from a plurality of second beams according to measurement results of the first information transmitted via more than two first beams; and a transmitting unit configured to transmit information about the preferred beam.

The invention claimed is: 
     
         1 . A first network device in a communication network, comprising:
 a receiver configured to receive measurement results of a terminal for first information transmitted via at least a part of first beams;   a processor configured to determine a preferred beam from a plurality of second beams according to measurement results of the first information transmitted via more than two first beams;   a transmitter configured to transmit information about the preferred beam;   the processor determines the preferred beam from the plurality of second beams according to the measurement results of the first information transmitted via more than two first beams by utilizing a correlation between the first beams and the second beams obtained in advance; wherein   the receiver is further configured to receive first historical measurement results of the first beams and second historical measurement results of the second beams, and   the processor obtains the correlation between the first beams and the second beams in advance at least according to the first historical measurement results of the first beams and the second historical measurement results of the second beams corresponding to the first historical measurement results.   
     
     
         2 . The first network device of  claim 1 , wherein
 the first network device is a network device provided in a core network above a base station of the communication network or a component corresponding to the core network,   the receiver receives the measurement results of the terminal forwarded by the base station for the first information transmitted via the at least part of the first beams, and   the transmitter transmits the information about the preferred beam to the base station.   
     
     
         3 . The first network device of  claim 2 , wherein
 the first network device is a data analysis device independently provided in a component corresponding to the core network above the base station of the communication network, or   the first network device is an element a device provided in the core network above the base station of the communication network.   
     
     
         4 . The first network device of  claim 1 , wherein
 the first network device is an intelligent analysis device provided in at least one of a centralized unit and a distributed unit of a base station.   
     
     
         5 . The first network device of  claim 1 , wherein
 the first network device is a wireless intelligent controller provided in at least one of a centralized unit and a core network.   
     
     
         6 . The first network device of  claim 5 , wherein
 the receiver receives the measurement results of the terminal forwarded by a distributed unit for the first information transmitted via the at least part of the first beams, and   the transmitter transmits the information about the preferred beam to the distributed unit.   
     
     
         7 . A beam selection method applied to a first network device in a communication network, the method comprising:
 receiving measurement results of a terminal for first information transmitted via at least a part of first beams;   determining a preferred beam from a plurality of second beams according to measurement results of the first information transmitted via more than two first beams;   transmitting information about the preferred beam;   the determining a preferred beam from a plurality of second beams according to measurement results of the first information transmitted via more than two first beams includes:   determining the preferred beam from the plurality of second beams according to the measurement results of the first information transmitted via more than two first beams by utilizing a correlation between the first beams and the second beams obtained in advance, comprising:   receiving first historical measurement results of the first beams and second historical measurement results of the second beams, and   obtaining the correlation between the first beams and the second beams in advance at least according to the first historical measurement results of the first beams and the second historical measurement results of the second beams corresponding to the first historical measurement results.
